Continuous venovenous hemodialysis (CVVHD) or hemofiltration conducted with pre- (CVVHpre) or post- (CVVHpost) dilution modes are recommended to treat patients with acute renal failure (ARF) and cardiovascular instability. The efficiency of the three techniques was compared in a study including 18 critically ill patients with ARF. Their mean age was 62.1 +/- 16.7 years, and their mean SAPS II score was 59.5 +/- 14.3. They were treated sequentially with the three techniques for periods of 24 hours each (randomized assignment to one technique the first 24 hours followed by the two others). The PRISMA device and M 100 (AN69S) membrane were used in all instances. Blood and replacement (or dialysis) flow rates were kept at 150 and 25 ml/min, respectively. Urea, creatinine, uric acid, inorganic phosphorus, beta2 microglobulin (beta2m), and retinol binding protein (RBP) were measured every 12 hours in plasma and in 12 hours filtrate collection for 3 days. The results are expressed as filtrate/mean plasma (F/P) ratio for the 12 hour period. Removal of small molecules was 16% higher using CVVHD and CVVHpost than CVVHpre. For beta2m and RBP, CVVHpre was, respectively, 43% and 26% more efficient than CVVHD. CVVHpost gave higher but statistically different removal than CVVHpre only for beta2m. CVVHpost was the most efficient technique for removal of small proteins, but this advantage could be easily counterbalanced using higher volume substitution.

Improved removal of small proteins using continuous venovenous hemofiltration to treat acute renal failure.

Plasma clearance of iohexol (PCI) is becoming a commonly used standard tool in many clinical trials to evaluate the glomerular filtration rate (GFR). However, most studies performing PCI use only early plasma samples (2, 3, and 4 hr). This study aims to evaluate the role of early and late plasma sampling in the precision of PCI calculation in transplant recipients.

Evaluation of sample bias for measuring plasma iohexol clearance in kidney transplantation.

Anodic aluminum oxide (AAO) films with different pore sizes were prepared to modulate the effective refractive index and birefringence. To investigate the relationship between the refractive index and the pore size of the AAO film, optical constants were obtained using a prism coupler with various lasers. With experimental results, the dispersion curve of alumina itself without pores was extracted using a theoretical anisotropic model. We demonstrated that AAO films could offer a wide range of refractive index and birefringence values for optical device applications. Furthermore, index profiles as a function of the thickness of the AAO films were obtained by inverse Wentzel-Kramer-Brillouin approximation to examine the optical homogeneity.

Effect of varying pore size of AAO films on refractive index and birefringence measured by prism coupling technique.

In this Letter, we have designed and fabricated a III-V semiconductor multilayer based on surface plasmon resonance (SPR) operating at the telecom wavelength. Optimization of the optogeometrical parameters and the metal/semiconductor layers required for this novel structure was conducted accurately by theoretical tools using the Maxwell equations. Technological fabrication of the device and its experimental characterizations using an evanescent coupling configuration was performed: the results have confirmed the existence of SPR associated to a sharp width response. This study could be a first step in the design of new plasmonic-semiconductor-based optical devices such as modulators and switches.
